I'm certain it has been in the past.No, it is not valid from either of those stations. It is valid on the Ebbw Vale Town branch, but only on trains that come from Cardiff and avoid Newport.
As with most rangers and rovers, you can undertake non-stop splits, although I'm not sure where you would want to do so at the moment. Of course, if Cardiff Parkway gets built, I could see the case for it if using XC (noting that it's not valid on GWR services).
Not in the 40 years since I first used it (or more pedantically its predecessor). Unless it’s had a brief period of validity which was then removed and I missed it. There have been debates in the past about what happens when Ebbw Vake trains are diverted via Newport….I'm certain it has been in the past.
Any idea when that changed?
It's one restriction which got mentioned to me when I purchased one a couple of months ago from the ticket office at Bridgend.I'm certain it has been in the past.
